SEDOLL Redefines Full-Size Doll Usability with Breakthrough "LSTPE" Lightweight Upgrade
Premier adult doll manufacturer SEDOLL today officially announced the rollout of LSTPE (Lightweight Super Soft TPE), an advanced structural option designed specifically for its flagship STPE body series. The new upgrade directly addresses one of the most significant pain points reported by full-size doll owners: heavy, unmanageable body mass during everyday use.
By integrating an internal structural foam core, the LSTPE option achieves a dramatic weight reduction of up to 11 kg (over 24 lbs) while preserving the signature softness, squish, and realistic flexibility that define the STPE series.
The Engineering Challenge: Softness vs. Weight
Full-size companion dolls have historically required collectors to make a choice between two primary materials: high-density silicone or soft TPE/STPE formulations. While silicone offers a drier, low-oil finish and lighter overall density, TPE and STPE remain the preferred choices for users seeking superior tactile elasticity, warmth, and lifelike skin deformation.
However, full-size STPE models often exceed 35 to 40 kg, making moving, dressing, and posing a challenging task for a single owner.
"Our primary engineering objective with LSTPE was simple," stated a senior product developer at SEDOLL. "We wanted to eliminate the physical strain of managing a full-scale companion without compromising the soft, realistic feel that makes STPE so popular. LSTPE brings lightweight construction to STPE bodies without turning the skin firm or sacrificing internal joint flexibility."
How LSTPE Works: Advanced Internal Architecture
LSTPE is not a new chemical compound or skin layer. Instead, it represents an architectural redesign inside the doll's body cavity.
Similar to the lightweight construction techniques developed for premium silicone models, LSTPE replaces dense internal TPE mass with a specially formulated, resilient foam core surrounding the internal stainless steel armature. This reduces central weight while keeping the external skin layer entirely authentic in look, feel, and elasticity.

Initial Launch Models & Weight Specifications
The initial phase of the LSTPE release supports three top-selling SEDOLL full-size body configurations:
| Body Model | Standard Weight | LSTPE Weight | Total Weight Saved |
| 157H | 41.0 kg (90.4 lbs) | 31.0 kg (68.3 lbs) | 10.0 kg (22.0 lbs / -24.4%) |
| 161F | 35.0 kg (77.2 lbs) | 31.6 kg (69.7 lbs) | 3.4 kg (7.5 lbs / -9.7%) |
| 163E | 37.0 kg (81.6 lbs) | 26.0 kg (57.3 lbs) | 11.0 kg (24.3 lbs / -29.7%) |
Note: Total weight reduction varies by model due to differences in internal body volume and skeletal placement. SEDOLL maintains a strict production quality standard ensuring actual weight variance remains within 5%.
Key Benefits of the LSTPE
1. Unmatched Handling & Mobility
Reducing body weight by 10 kg or more transforms the daily ownership experience. Tasks like changing outfits, cleaning, repositioning, and moving the doll between rooms require significantly less effort.
2. Uncompromised STPE Softness
Unlike older methods of weight reduction that relied on firmer materials, LSTPE preserves natural elasticity across high-touch areas including the bust, waist, abdomen, and hips.
3. Low-Oil Surface & Easy Maintenance
LSTPE retains the lower-oil, drier surface properties of SEDOLL's STPE line, reducing powdering frequency and minimizing friction when dressing in delicate garments.
4. Cross-Material Compatibility (Silicone Head Pairing)
SEDOLL has successfully color-matched the Light Tan LSTPE Body with its Light Tan Silicone Heads. Because silicone and TPE reflect light differently, specialized color adjustments are applied during production to ensure seamless head-to-body tone blending.
Availability & Future Roadmap
The LSTPE Lightweight Upgrade is available for custom selection on the 157H, 161F, and 163E body models. SEDOLL has confirmed plans to expand the LSTPE option to additional body shapes and launch expanded cross-material color matches throughout the coming months.
Ready to Experience a Lighter Full-Scale Companion?
The SEDOLL LSTPE Lightweight Upgrade is available now on select full-size models. If you love the soft, lifelike feel of Superior TPE but want a doll that is significantly easier to dress, move, and handle solo, LSTPE offers the ultimate balance of comfort and convenience.
